This study reports the treatment of two patients with single tooth scissors bite. The first patient had a scissors bite which affected the two first premolars. The second patient had buccal crossbite in the second left molar. The cause of this malocclusion was the buccal tipping of the upper teeth. Modification of the palatal arch was used in the treatment therapy. This modification allowed for the palatal movement and intrusion of the affected teeth. Changes in certain dental arch parameters were observed during both the active and post treatment period. Premolars were correctly positioned within 1.5 months and 2 months. The molar was well positioned within 2.5 months. Correct intercuspidation of the opposing teeth was the only form of retention. During the 2.5 years of the observation period there was no recurrence of the malocclusion.

Key words: scissors bite, modified palatal arch, dental arch parameters, active treatment, post treatment observation.
